Decreased GA:ABA hormone ratio in light-exposed Aethionema CYP seeds. Hormone concentrations [in pmol g^–1 dry weight (DW)] of GA₉ precursor, bioactive GA₄, and GA₃₄ catabolite (A) and ABA (B) are shown for dark-exposed (grey columns) and light-exposed (cream columns) TUR and CYP seeds. (C) Ratio of the averages from GA₄ and ABA measurements. Significance was tested using the Welch test in pairwise comparisons; asterisks indicate significant differences: *P<0.05, **<0.01. Error bars represent SD (five independent replicates). Values for other GA metabolites are presented in Supplementary Fig. S4.
